ULTRASONIC FAULT DETECTING DEVICE

摘要

PURPOSE: An ultrasonic test machine is provided to obtain accurate pulse data and to reduce the extent of the abrasion of an ultrasonic fault detecting probe. CONSTITUTION: An ultrasonic test machine comprises an ultrasonic fault detecting probe, a housing unit(120), a pin(130), a guide, a compressive spring(150), a ball joint(160), and a roll(170). The ultrasonic fault detecting probe contacts to a shaft to be tested. A groove is formed in the housing unit so that the ultrasonic fault detecting probe is downwardly received in the housing unit. The pin is fixed to the housing unit, thereby being upwardly extended. The compressive spring is interposed between the guide and the housing unit so that the pin is fitted into the compressive spring. The ball joint connects the guide and the housing unit.
